Abstract
Description
- The present invention relates to a method of manufacturing footwear made up of an injected underpart and an upper formed by pieces made of natural or synthetic leather, elastic, adornments, etc.
- More specifically, the method of the invention is envisaged for the manufacture of footwear of the described type in which the upper, formed by more than one piece, lacks seams.
- The manufacture of footwear by traditional methods comprises the following operations:
- Cutting pieces of upper which will form the top part of the footwear.
- Manually joining these pieces to one another by means of glues, seams, including reinforcements and decorative elements, etc.
- In addition, a process is performed, which is the manufacture of the midsole, which requires the upper and the forming thereof on the inner surface of the last.
- Preparation processes are then performed for the assembly, such as the placement of reinforcements in the back and front part that will form the counter and tips.
- Fixing the insole on the inner surface of the last with staples or tape.
- Assembling the different components, for which different alternatives are possible, the most common being machine assembly, where the upper is placed on the last, with the midsole thereunder.
- Introducing the assembled set into a forming oven so that the materials stabilize and conserve the shape.
- Scouring the grain side of the upper with the shape of the sole previously marked thereon.
- Applying glue to the scoured part and also to the sole, chemically prepared previously for the anchoring of the glue.
- Separately manufacturing, generally through auxiliary companies, the sole made up in most cases of injection materials.
- Gluing the sole by means of a correct positioning and application of pressure to the machine.
- Removing the finished footwear from the last for subsequent cleaning and application of some type of final finish.
- The described process involves a large number of operations and requires a considerable amount of manual labor, making the manufacture of the footwear much more expensive.
- The object of the present invention is a method of manufacturing footwear by means of a reduced number of operations in comparison with traditional processes, thereby allowing the reduction of manufacturing costs.
- Another object of the invention is to obtain footwear with a different and more attractive appearance than that of footwear obtained by traditional methods.
- The manufacture of footwear with the method of the invention is carried out by means of the following steps:
- a) Cutting the pieces that will form the upper of the footwear.
- b) Preparing a mold and counter-mold, which mold is made up of two or more parts which internally reproduce the outer configuration of the footwear in its entirety, upper and underpart, and have areas the contour of which corresponds to that of the pieces that will form the upper of the footwear. The counter-mold adopts the shape of a metal last and demarcates with the inner surface of the mold cavities that will correspond to the volume of the upper and underpart.
- c) Placing the pieces that will form the upper of the footwear in the areas defined inside the mold, from which they will project to demarcate empty cavities and channels.
- d) Injecting a thermoplastic material in molten state into the mold until filling all the cavities and channels demarcated by the pieces that will form the upper and coming into contact with said pieces.
- e) Opening the mold and extracting the last constituting the counter-mold, thus providing the finished footwear.
- The method of the invention with the described steps allows eliminating virtually all the operations of the traditional methods, thereby allowing greatly reducing the manual labor cost.
- In the method of the invention the inner surface of the parts forming the mold reproduces the total volume of the footwear, including the upper and the underpart. The areas reproducing the upper have a topography comprising areas separated by ribs of little height, in which areas the pieces of the upper, of greater thickness than the ribs, are placed, said pieces demarcating a network of channels and cavities, including the volume corresponding to the underpart which, when injecting the thermoplastic material in molten state, configures a skeleton that is in contact with the pieces of the upper in order to serve as a joining means between them while at the same time forming the underpart or sole of the footwear with which the aforementioned skeleton is connected.
- The areas intended for receiving the pieces that will form the upper, demarcated by the aforementioned ribs, will have fixing means for fixing said pieces in order to assure their positioning during the injection of the thermoplastic material. These fixing means can consist of an adhesive coating with reduced fixing capacity which will cover at least part of the surface of the aforementioned areas. The aforementioned fixing means can also consist of small pointed projections, like small needles, projecting from the surface of the aforementioned areas and the height of which will be smaller than the thickness of the pieces which will form the upper of the footwear.
- The pieces that will form the upper are placed in an inverted position when the mold is open. Once all the components of the upper are placed, the different parts forming the mold are coupled on the metal last which acts like a counter-mold, the mold set being closed in order to inject the thermoplastic material in molten state. Then, once the injected material is cured, the mold is opened, the last is removed from the footwear and finished footwear with formed upper and sole is provided, with the general appearance of traditional footwear but with its own special character because it will be lacking seams, thereby giving the top visible surface of the footwear a different appearance.
- As can be understood, any other component can be applied on the footwear obtained by the method of the invention by means of sewing, riveting, etc.
- In the method of the invention, a coating of a suitable material can be applied on the surface of the last prior to injection, for example based on a leather or fabric liner which would be in contact with the grain side toward the last and the flesh side toward the fluid. Footwear with an upper and a liner would thus be obtained, and the ribs of the thermoplastic material would also remain concealed between liner and upper. In other words, when looking at the inside of the footwear, only the liner would be seen rather than the flesh side of the leather of the upper and the ribs of thermoplastic materials joining the pieces of said upper to one another. Seams can be used in this liner for its formation.
- The method of manufacture of the invention is depicted in the attached drawings given by way of non-limiting example, in which:
-
Figure 1 is a plan view of a mold used for manufacturing footwear according to the invention. -
Figure 2 is a longitudinal section of the mold and last which acts like a counter-mold, taken along section line II-II ofFigure 1 . -
Figure 3 corresponds to detail A ofFigure 2 on a larger scale. -
Figure 4 shows a side elevational view of the position of the different pieces forming part of the upper of the footwear. -
Figure 5 depicts the network of ribs and underpart obtained when injecting the thermoplastic material into the matching last and counter-last set ofFigure 2 . -
Figure 6 shows a side elevational view of footwear obtained with the method of the invention. - The manufacture of footwear by means of the method of the invention is performed with a mold and counter-mold depicted in
Figures 1 to 3 . - The mold will reproduce the outer surface of the footwear to be manufactured, including the underpart, and will be made up of at least two
parts 1 and 2 which, when closed, will demarcate a cavity that will correspond to the outer configuration of the footwear. This mold can be made up of a greater number of parts which can be coupled to one another. - A metal last 3 which acts like a counter-mold is housed inside the mold formed by
parts 1 and 2, such that between the outer surface of the last and the inner surface of theparts 1 and 2 forming the mold there is demarcated a space which will correspond to that of the footwear, including the upper and underpart. - In the example depicted in the drawings, part 1 of the mold is what will demarcate, together with the last 3, the cavity for the sole of the footwear, where as the space demarcated between
part 2 and the last 3 corresponds to the volume of the upper. - According to the invention,
part 2 has on itsinner surface areas 4, the contour of which corresponds to that of the pieces that will form the upper of the footwear, areas which are separated and demarcated byribs 6,Figure 3 . - There are arranged in all the areas of the inner surface of
part 2 of the mold, corresponding to pieces of the upper and generally indicated inFigures 2 and 3 withreference numbers reference numbers ribs 6, such that betweenconsecutive pieces cavities 10, which will correspond to the peripheral areas of the footwear or underpart, are demarcated between the last 3 andpart 2. Finally, acavity 11, which will correspond to the volume of the underpart of the footwear, will be demarcated between the last 3 and part 1. - By way of example,
Figure 4 depicts the relative position that thedifferent pieces - The pieces forming the upper can be of natural or synthetic leather, can include elastic, decorations, etc., in each case being placed in areas or cavities formed in the inner surface of
part 2 of the mold. - Once all the pieces of the upper are placed and the mold is closed with the last inside it, a thermoplastic material in molten state is injected, there being produced, through the network of channels 9 and
cavities Figure 5 , between the ribs of which thepieces Figure 4 will be located. The skeleton ofFigure 5 , together with the underpart obtained in the same injection operation, withoutpieces - Due to the shape of the channels 9 together with the
cavities ribs 6 do not reach the surface of the last 3, the molten thermoplastic material which is injected into the closed mold is in contact with thepieces - When opening the mold and extracting the last 5 footwear such as that depicted in
Figure 6 is obtained, in which thepieces intermediate ribs 14 and, in the depicted example, by thearea 15 of counter and sole 16, made from the injected thermoplastic material. - The footwear of
Figure 6 , as it is obtained when opening the mold, will be ready for coupling the insole thereto and for cleaning products without requiring sole stitching, assembly, forming and gluing operations which are necessary in traditional methods. - As mentioned above, a coating which will be fixed to the inner surface of the pieces forming the upper, acting like a footwear liner, can be applied on the surface of the last 3.
